S14 Convenient Switches
Magnum S14-Series units are plug-and-play devices. There is no software
configuring to be done at installation or for maintenance. The only hardware configuration
settings is user options for port#2, to configure at FF/AN and can be done through a manual
switch accessed from the front side. The internal functions of both are described below.
Switching, Filtering and Forwarding
Each time a packet arrives on one of the switched ports, the decision is taken to
either filter or to forward the packet. Packets whose source and destination addresses on
the same port segment will be filtered, constraining them to one port and relieving the rest
of the network from processing them. A packet whose destination address is on another
port segment will be forwarded to the appropriate port, and will not be sent to the other
ports where it is not needed. Packets needed for maintaining the operation of the network
(such as occasional multi-cast packets) are forwarded to all ports.
